3-Deoxyanthocyanidins are a rare type of flavonoids restricted to a few plant species. They are the major pigments in flowers of sinningia (Sinningia cardinalis) and are found in silk tissues of certain maize lines. Sorghum is the only dietary source for 3-deoxyanthocyanidins, which are present in large quantities in the bran of some cultivars . Many plants use secondary metabolites to protect themselves against pathogen attack. In sorghum, this defense response is an active process resulting in the accumulation of high levels of 3-deoxyanthocyanidin phytoalexins in infected tissues. Luteolinidin and apigeninidin are the two major 3-deoxyanthocyanidins. Flavonoids are increasingly recognized for their range of health benefits, such as reducing the risks of cardiovascular diseases and cancers due to their antioxidant, anti-inflammatory, and chemoprotective properties. In particular, anthocyanins and anthocyanidins from different sources were shown to suppress proliferation and induce apoptosis in cancer cell lines. In a recent study, 3-deoxyanthocyanidins were found to have antioxidant properties similar to those of anthocyanins, but they are more stable to power of hydrogen, temperature, and light changes,suggesting that they could serve as an alternative source of natural pigments with nutraceutical properties.
